• Performing a fuzzy search may retrieve terms with similar spellings: "((werner von) OR (werkes von)) siemens ((rging" OR rgingoe") OR ((gingee" OR ggingee") OR ing"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((werner von) OR (werkes von)) siemens ((rging\" OR rgingoe\") OR ((gingee\" OR ggingee\") OR ing\"))".
• Removing quotes may allow a broader search: ((werner von) OR (werkes von)) siemens ((rging OR rgingoe ) OR ((gingee OR ggingee ) OR ing )).
• Adding a wildcard symbol may retrieve word variants: "((werner von) OR (werkes von)) siemens ((rging" OR rgingoe") OR ((gingee" OR ggingee") OR ing"))*.
